      Do you know Weibo? Do you write a Weibo? If you don't, you are “out”! Weibo means microblog. People may spend much time writing a blog, but it takes a little time to write a microblog. Why? Because every message on a microblog is less than 140 words.

      Microblog started in the USA. It came to China in 2009 and it has developed very fast. In 2011, the number of Chinese microbloggers grew to 300 million. Now more and more people are interested in writing microblogs. For many microblog users, it is a great way of learning the freshest news, talking with friends and sharing different kinds of information, including news, daily life, pictures, music and so on. Many stars and famous people also write microblogs and share good things with their fans.

      It is easy and fast to send a message on a microblog. However, this can also lead to problems and even cause panic. For example, when the big earthquake and tsunami (海啸) hit Japan in March, 2011, messages like “Salt can protect people from radiation” were hot on microblogs. It soon caused a crazy buying of salt. Later people realized it was just a rumor(谣言).

      In a word, microblog plays a new role in the life of Chinese people.

    In the future, some tiny computers would be put in our heads. This can help people a lot. 1 the tiny computers, the people who have ear disease will be able to hear. And those with eye diseases can 2. The tiny computers will not be just for 3 people. Most of us will have one to make our life 4. For instance, if we have it, we will be able to think 5 and we can memorize more.

    For every student，computers can do 6 things. Perhaps in the near future, they 7 schoolbags. The students just need to carry a small computer to 8, because the computer takes the place of the textbooks, exercise books and note books. The teachers will check their homework with computers, 9. But this can cause another problem because 10 will be easier for students to copy each other's homework.

      George Devol who came from the USA designed the first programmable robot in 1969. It meant that the robot age had started from then on. However, in about 989 BC, during western Zhou Dynasty, a Chinese man whose name was Yan Shi made a wood robot. It looked like a real man and it was able to do many actions. It was good at dancing and it has a heart, a stomach and other things in its body. It also had teeth and hair. It could express its feelings by using its eyes. Its eyes could move and could show love to women, but it couldn't laugh. It was probably the earliest robot in the world.

      Not all robots always look like humans. They have various shapes. They are clever and they can do all kinds of jobs, especially difficult and dangerous jobs. They are widely used in factories, banks, hospitals and other places. In the future, robots will make fewer mistakes, even can correct themselves and they will be smarter. It's possible that we will have a robot in our own home. They will do more things for us. We will have more free time to have a rest, to relax ourselves with the help of robots. I believe that we can have a better life.
